What is the Best Backpacking Water Filter | Buyer Reviews

best backpacking water filter

Pure clean water is very important for outdoor activities. Not only is it refreshing to drink, but it keeps you hydrated and protects you from heat stroke and exhaustion.

Unlike whole house water filters and other residential water filters, portable water filters can be easily taken along with your camping gear to provide safe drinking water when you're out and about. 

Finding the best backpacking water filter for your needs shouldn’t be difficult. You could just go to a store near you and pick up the first backpacking water filter you see. Better yet, you’ll probably want to research the backpacking water filter reviews online to save yourself time and money in the long run.

Backpacking water filters come in different sizes, shapes, weights, abilities, and styles. There are pump filters and gravity filters. There are filters that eliminate protozoa, bacteria, and viruses. In the end, you need to identify your needs before buying a backpacking filter.

Ultimately, the final decision is yours to make. To help you find the best backpacking water filter, here are some important factors you should consider.


• Weight - This is an important factor particularly on a long-distance excursion. When it is not always the case, there tends to be a compromise between weight and filtering speed. The smaller and lighter the water filter is, the longer it takes to purify.

• Speed - Some water filters are fast, while others will take a lot of your limited backpacking time. Know how many people will be drinking the water. Water filters that use chlorine or iodine to filter the water can take 4 hours to purify, while others take only a few minutes. You want to remember the fun times during your trip, not the long waiting process of filtering your water.

• Type - There are several types of water filters for backpacking. There are simple filters that let you sit back and relax while the water is filtering. Gravity type filters use gravity to purify water from one bag to another. Other filters need constant involvement, which means you have to either squeeze or pump the water. Some water filters are made out of ceramic and are not recommended to be exposed to a very cold environment.

• Source - Backpacking water filters can also depend on the kind of water you are filtering. Various elements can contaminate water in different ways, like leaf debris or mud caused by a recent heavy rain, etc.

Product Overview

When it becomes clear as to what you need from a water filter, then it is time to pick the right model. It can be overwhelming since there are a lot of good brands on the market. To give you a good start, here is my recommendation of the best water filter for backpacking.

Platypus GravityWorks 2.0 Bottle Kit

Winning many awards, Platypus GravityWorks 2.0 Bottle Kit is my ultimate choice for a backpacking water filter. Since it is a gravity filter, it depends on gravity to push water through, removing the need to manually pump the water. It easily treats small or large amounts of water quickly. It is also extremely compact and works well for a large group of backpackers. Despite its small size, it is surprisingly one of the fastest products for filtering water. It is the ideal choice for purifying large quantities and needs little to no maintenance. Overall, the whole GravityWorks kit weighs only 9.5 ounces.

● Clean water bag with hanging strap, buckle, hose shut-off clamp for storing and distributing water and a screw on hose adaptor for a tight seal

Pros and Cons

 What I love about the Platypus GravityWorks 2.0L water filter is its simple set-up. It has a instinctive color-coding system (gray for dirty water; blue for clean water) and useful instruction manual. The storage sack provided can comfortably fit all the tubes, filters and reservoirs. This allows for safe transport of the water filter without damaging it.

Using the water filter is as simple as gliding along a water surface to fill the "dirty" supply. I am amazed at its flow rate of 2.5 minutes for the full bag. Its pros go beyond its fast performance. It has the convenience of not having to manually push the water through the filter and the ability to filter water for a large group of people.

The weight and size of storage are reasonable for the filter's capacity and output. The tubes bundle tidily around the filter itself and it is fairly easy to roll the reservoirs throughout the filter. This makes it easy to place everything into the storage bag.

The main issue with the filter is common among similar water filters: getting water from non-flowing sources. You will have to find a moving water source to be able to use the system. For some people, especially ultra-light backpackers, the whole system may be too heavy.


Ultimately, I believe that the Platypus GravityWorks 2.0L is the best backpacking water filter available. If you are searching for a water filter that can effectively complete your backpacking needs, this is the one you should choose. Because of it's portability, I recommend it highly to friends and family for outdoor use. If you are searching for a water filter that can effectively complete your backpacking needs, this is the one you should choose.
